Except most PSU, esp modded, and equipment designed for international markets, will use an IEC plug-in cable - there's nothing to stop a 15A-provisioned cable being plugged into kit capable of drawing 20A. My 2400W ex-Dell pair draws 11A on 240v when loaded to 100A output (2400W out @ 90% eff into 2 x PL8), but 17A on 110v (1500W out, 63A max, as measured) as efficiency drops to 75% at the lower input voltage. The IEC cable is labelled "15A max" but the only way to ensure that would be to manually limit the dual-PL8 input current to 2 x 27.5A @ 24v (or 1 @ 35A and 1 @ 20A, etc). Of course a single PL8 will never exceed 50A input anyway (13.6A @ 110v).

Has anyone tried the 50 amp charger the company is selling? The price of it is somewhat reasonable compared to the other chargers I’ve seen for sale. I’ve also read on this site variable voltage chargers are better to have. Also I see that many chargers now offer three stage charging. Does anyone know if they are any good? I want to buy a pl8 so that I can do some Odysseys now and get to lithium in a year or two. I’m thinking a three stage charger is not the thing to use with a pl8. Some of them are very expensive also. Does anyone have any opinions to share?

They have a specific switch for 24v GEL that seems ensure correct values, but I may be wrong.
Than you!
As the capacity is fully restored, the charging current starts reducing. When the cur-rent reduces below the preset threshold (1.5 to 2A for SEC-1215UL / 2415UL and 2.5 to 3A for SEC-1230UL), the charger automatically switches to the "Float or Maintenance Stage"

Only you can decide what you are capable of, but don't generalise. Many disabled people can manage far more than they imagine, once they put their mind to it. I'm a 61y old quad/tetra with zero hand function but I've re-engineered 2 chairs, built a lithium pack, mentor 2 students at the local Academy, I teach basic mechanics and basic electronics to MSc students at the research labs associated with the spinal unit, where I also act as an ambassador in the "art of the possible". Oh and I'm currently doing a PhD and, as a sideline, reverse engineering the R-Net programmer ...arguably I'm doing much more now than when I was employed before my accident 7y ago!

It wants to switch from the 28.00V to 27.00V when current drops to around 1/3rd of an amp. 200 to 350mA. Or 8 hours max, whichever occurs frst. But it doesent say... So it may be perfect. Or it may be better than most! We cant know because aparently we are all to stupid to be given the real data.

I was only talking about physical ability. I have a PhD and have been an Associate Professor during 15 years when I was living in France, including 7 years on a wheelchair. But many disabled cannot plug their charger, this is a reality. Others can.

And so was I. I 'work' in the research labs linked to the London Spinal Cord Injury Centre and liaise with many newly injured people. And yes, it's true that some cannot physically do some things. But I would contend, from personal experience, that many can do far more than they think they can, once shown how, or provided with a simple assitive device.
I have no hand function, I cannot hold anything, yet I manage far more than many supposedly less injured, by finding alternative approaches to the problem. For the first 6mo post injury I was in a very negative frame of mind but fortunately I managed to get past it thanks to many at the spinal unit and support from my friends at ASPIRE and the local SIA guys. For many the more serious 'injury' is a mental block - as organisations such as SIA & Backup work to overcome - and many that come to the spinal unit have been 'told' by the trauma team and quite often their relatives that they'll never do 'X' again. Well maybe not in the same way, but there's more than one way to skin a cat (not that I condone the action )
I agree! The environment also matters. I left France, a country where you have plenty of financial support for disabled, because of people. Ableism is the norm in France.
I moved to the U.S. to escape from this situation. Now I'm not getting money (except from my own work and efforts), but an amendment protects me, and more generally the local culture makes my life easier.
